Summary: Heterostructures consisting of CuGaO2 nanosheets and TiO2 nanoparticles were synthesized through a one-pot hydrothermal method. The CuGaO2/TiO2 heterostructure exhibited a higher photocurrent density and tetracycline hydrochloride degradation efficiency compared to pristine CuGaO2 nanosheets and TiO2 nanoparticles. Experimental characterizations and density functional theory calculations showed that the built-in electric field in the CuGaO2/TiO2 interface region promoted the separation of photogenerated carriers.

Summary: The titanium dioxide photocatalyst is only active under UV irradiation, but a new excitation pathway called interfacial charge transfer (IFCT) has been found to activate copper(II) oxide nanoclusters-loaded TiO2 powder (Cu(II)/TiO2) for organic decomposition under visible-light irradiation. A photoelectrochemical study showed that the Cu(II)/TiO2 electrode exhibited a cathodic photoresponse under both visible-light and UV irradiation, generating H-2 evolution on the electrode. This study demonstrates a direct interfacial excitation-induced cathodic photoresponse for water splitting without the need for a sacrificial agent, which can contribute to the development of visible-light-active photocathode materials for fuel production.

Summary: The photoresponse of TiO2 nanotube photoanodes is significantly influenced by the illumination intensity, with a significant increase in IPCE magnitude as the illumination intensity decreases. Higher illumination intensities lead to hole accumulation and trapping. At low light intensities, there are noticeable changes in IPCE spectra and a slowing of transient photocurrent kinetics.

Summary: An Ag-modified TiO2 nanomaterial was synthesized using a one-pot method. The structure and morphology of the synthesized material were determined using X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The results showed that the addition of metallic Ag nanoparticles decreased the optical band gap and photoluminescence intensity of TiO2, while increasing the Raman peak intensity and absorbance. The Ag-modified TiO2 nanomaterial exhibited higher photocatalytic efficiency than bare TiO2 and Ag metal NPs, attributed to the synergistic effect between Ag metal and TiO2 structures.

Summary: The study suggests that octahedral nanocubes with abundant {101} facets in anatase TiO2 nanocrystals produce over 4 times more H2 in photocatalytic H2 evolution compared to nanosheets enriched in {001} facets under co-catalyst-free conditions. However, when samples carry Pt co-catalyst on both {001} and {101} facets, the significance of faceting diminishes, indicating that the beneficial role of faceting is relevant only for co-catalyst-free surfaces.
